# If the Distance Between Points (X, 0) and (0, 3) is 5, What Are the Values of X? - Mathematics

Short Note

If the distance between points (x, 0) and (0, 3) is 5, what are the values of x?

#### Solution

We have to find the unknown x using the distance between A( x , 0)   and B ( 0 , 3 ) which is 5.In general, the distance between A(x_1 , x_2 )  and B (x_2 , y_2)   is given by,

AB = sqrt( ( x_2 - x_1 )^2 + (y_2 - y_1)^2)

So,

5 = sqrt ( ( x -  0)^2 +  ( 0 -3 )^2 )

Squaring both the sides we get,

x^2 - 16 = 0

So,

x = +- 4

Is there an error in this question or solution?
